[Stimulation of mucoperiostal slice epithelization by small power laser after the primary plastic of oroantral communication].

INTRODUCTION: The oroantral communication is a pathologic communication between the oral cavity and maxillary sinus. It originates with extraction of the upper lateral teeth. Primary plastics communication, which is more extensive than 5 mm has been unsuccessful in 16%. Small power lasers have positive reaction on wounds healing. The aim of this work was to determine the lasers effects on slice epithelization after the plastics more extensive than 5 mm. MATERIAL AND METHODS: The experimental research was done on dogs with extraction of the upper second premolars on both sides, and formed oroa

Extended Platelet-Rich Fibrin as a Membrane for Lateral Window Sinus Lifts: A Case Series.

INTRODUCTION: Platelet-rich fibrin (PRF) is being increasingly utilized in surgical procedures due to various improvements in clinical outcomes. More recently, a heating process to denature albumin in the platelet poor plasma (PPP) layer has been shown to extend the resorption time of PRF from a typical 2-week period to 4-6 months. Because of its > 4 month resorption properties, extended PRF (e-PRF) membranes have been used in dentistry as an alternative to collagen membranes in alveolar ridge preservations, ridge augmentations, soft tissue grafting, and as a barrier membrane in lateral sinus

PATIENTS AND METHODS: A retrospective case series study design was implemented that included patients who received zygomatic implants identified in the database of the Department of Oral and Maxillofacial Surgery, Universidad El Bosque from 2009 to 2013. Contact information was retrieved from the charts and patients were asked to attend the department for a follow-up appointment. The populatio

Unilateral sinonasal symptoms.

OBJECTIVE: The aim of the study was to describe the pathology in patients with unilateral sinonasal symptoms and to identify variables that may predict neoplastic pathology. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective analysis was completed on 207 consecutive patients with sinonasal symptoms, most of whom underwent functional endoscopic sinus surgery from 2005 to 2008. Of the charts reviewed, 63 patients had unilateral sinonasal symptoms with unilateral opacification of paranasal sinus computed tomography scans. Presenting symptoms and radiographic, surgical, and patho

Rare Diseases of the Nose, the Paranasal Sinuses, and the Anterior Skull Base.

Due to their low incidence and thus resulting limited diagnostic criteria as well as therapeutic options, rare diseases of the nose, the paranasal sinuses, and the anterior skull base are a significant challenge. The value as of which a disease has to be considered as rare amounts to a maximum of 5 patients per 10 000 people. Within these diseases, however, there are extreme differences. Some rare or orphan diseases like for example the inverted papilloma belong to regularly diagnosed and treated diseases of larger departments of oto-rhino-laryngology whereas other rare diseases and malformati

Risk Factors of Membrane Perforation and Postoperative Complications in Sinus Floor Elevation Surgery: Review of 407 Augmentation Procedures.

PURPOSE: To test patient- and sinus-related risk factors for an association with intraoperative membrane perforation and postoperative complications after sinus floor augmentation surgery. MATERIALS AND METHODS: Sinus floor elevation procedures using a lateral approach were retrospectively analyzed for patients' medical history and sinus anatomy on computed tomographic scans.

Antimicrobial treatment guidelines for acute bacterial rhinosinusitis.

UNLABELLED: Treatment guidelines developed by the Sinus and Allergy Health Partnership for acute bacterial rhinosinusitis (ABRS) were originally published in 2000. These guidelines were designed to: (1) educate clinicians and patients (or patients’ families) about the differences between viral and bacterial rhinosinusitis; (2) reduce the use of antibiotics for nonbacterial nasal/sinus disease; (3) provide recommendations for the diagnosis and optimal treatment of ABRS; (4) promote the use of appropriate antibiotic therapy when bacterial infection is likely; and (5) describe the current underst

Strategy to select nasopharyngeal cancer patients for adaptive radiotherapy.

BACKGROUND: Nasopharyngeal cancer (NPC) patients experience significant anatomical changes during radiation treatment (RT). Adaptive radiotherapy (ART) can be initiated in response to specific events or at scheduled intervals during treatment, prompting questions about patient selection, timing, and reliable triggers for re-CT and replanning. This study aimed to develop a method for selecting NPC patients for ART before treatment and identify the optimal timing for its implementation. MATERIALS AND METHODS: We retrospectively evaluated NPC patients treated at University Hospitals Leuven betwe

The Endoscopic Versus Open Approach for Anterior Skull Base Tumors: A Systematic Review of Comparative Outcomes and a Framework for Surgical Selection.

BACKGROUND: Anterior skull base tumors (ASBTs) pose significant surgical challenges due to their proximity to critical neurovascular structures. Surgical management has evolved with the adoption of both endoscopic and open approaches. This systematic review synthesizes evidence comparing these approaches in terms of complications, outcomes, and indications. METHODS: We conducted a systematic review following the PRISMA guidelines, analyzing studies published between 1981 and 2022. A total of 1200 articles were initially identified from databases including PubMed, MEDLINE, JSTOR, and ScienceDi

Multicenter Survival Analysis and Application of an Olfactory Neuroblastoma Staging Modification Incorporating Hyams Grade.

IMPORTANCE: Current olfactory neuroblastoma (ONB) staging systems inadequately delineate locally advanced tumors, do not incorporate tumor grade, and poorly estimate survival and recurrence. OBJECTIVE: The primary aims of this study were to (1) examine the clinical covariates associated with survival and recurrence of ONB in a modern-era multicenter cohort and (2) incorporate Hyams tumor grade into existing staging systems to assess its ability to estimate survival and recurrence. DESIGN, SETTING, AND PARTICIPANTS: This retrospective, multicenter, case-control study included patients with ON

Study of Profile of Mucormycosis During the Second Wave of COVID-19 in a Tertiary Care Hospital.

Introduction and aim Mucormycosis is a lethal opportunistic infection caused by filamentous fungi of the family Mucoraceae (black fungus). There has been a sudden increase in the incidence of these cases during the second wave of the COVID-19 pandemic due to the immunocompromised state caused by the disease and its treatment. Early diagnosis and appropriate medical management are essential to reduce disease morbidity and mortality. Through this study, we aim to study the clinical features, risk factors, laboratory investigations, and radiological findings of patients with mucormycosis as well

Facial Fractures and Mixed Dentition - What Are the Implications of Dentition Status in Pediatric Facial Fracture Management?

INTRODUCTION: The stage of maturation of the pediatric facial skeleton at the time of injury has a significant impact on both facial fracture patterns and management strategies. For instance, the relative prominence of the pediatric cranium during the early years of life affords protection to the structures of the midface, whereas delayed aeration of the frontal sinuses may predispose younger patients to frontal bone fractures. The dentition status of a pediatric patient may have similar implications in the setting of facial fracture. In this study, the authors examine the effect of dentition

Sinonasal tract mucoepidermoid carcinoma: a clinicopathologic and immunophenotypic study of 19 cases combined with a comprehensive review of the literature.

Primary sinonasal tract mucoepidermoid carcinomas (MEC) are uncommon tumors that are frequently misclassified, resulting in inappropriate clinical management. The design of this study is retrospective. Nineteen cases of MEC included 10 females and 9 males, aged 15-75 years (mean, 52.7 years); males, on average were younger by a decade than females (47.2 vs. 57.7 years). Patients presented most frequently with a mass, obstructive symptoms, pain, and/or epistaxis present for a mean of 12.6 months. The majority of tumors involved the nasal cavity alone (n=10), maxillary sinus alone (n=6), or a co

A rare case of diffuse large B-cell lymphoma of the frontal sinus and rapid review of literature.

INTRODUCTION: Primary lymphoma of the paranasal sinuses, especially involving the frontal sinus, is exceedingly rare. Extranodal non-Hodgkin lymphoma (NHL) located in the head and neck frequently poses diagnostic challenges because its nonspecific symptoms can be mistaken for benign issues such as rhinosinusitis. AIM: This case report seeks to emphasize the challenges in diagnosis, the aggressive characteristics, and the effective treatment of an uncommon manifestation of diffuse large B-cell lymphoma (DLBCL) primarily affecting the frontal and ethmoid sinuses. CASE PRESENTATION: We present
